1. The diameter of a circular tray is 28 cm. Findthe area of the tray (Take at = ??]A. 44 cmB. 88 cmC 154 cmD. 616 cm

Answer 1

`\text{Area of the tray = 616 cm (Option D)}`

Let d represent the diameter of the circular tray

`d\text{ = 28 cm}`

The area of a circle is given by the formula:

`\text{Area, A }=\text{ }(\pi* d^2)/(4)`
`Take\pi\text{ = 3.142}`
`A\text{ = }(3.142*28^2)/(4)`
`A\text{ = }(3.142*784)/(4)`
`A\text{ = }(2463.33)/(4)`
`A\text{ = }615.83\text{ cm}`
`A\text{ = 616 cm (to the nearest whole number)}`
